Common Chimney Issues in Gaithersburg

Many Gaithersburg homeowners convert wood-burning fireplaces to direct-vent gas. Properly sized stainless steel liners prevent condensation damage.

Older Gaithersburg brick chimneys benefit from ChimneySaver vapor-permeable waterproofing with 10-year warranty to stop further freeze-thaw spalling.
Gaithersburg Housing & Chimneys

Montgomery Village features 1970s-80s townhomes and single-family homes with two-flue chimneys. Washingtonian and Lakelands offer 1990s-2000s homes with three-flue brick chimneys.
